S1221
OC-3/12 SONET/SDH 8-bit Quad Transceiver
Features
Description
• CMOS 0.13 micron technology
• Complies with Bellcore and ITU-T specifications for jitter tolerance, jitter transfer, and jitter generation
• On-chip high-frequency PLLs for clock generation and clock recovery
• Supports Data Rates for 155.52 Mbps (OC-3)
and 622.08 Mbps (OC-12)
• 8-bit LVCMOS Parallel data path
• LVDS or LVPECL differential serial interface
• Internal termination of the optic’s LVPECL
driver renders a seamless power saving connection
• Typical 715 mW power in LVDS I/O mode
• Directly compatible with 2.5 V or 3.3 V LVDS,
3.3 V LVPECL (DC and AC)
• Frame and Byte Boundary Detection option
• 255 PBGA Package,17x17 mm2 with Green/
RoHS compliant lead free option
• 1.2 V and 3.3 V/2.5 V supply
• Receiver lock detect outputs
• Signal detect inputs
• Selectable reference frequencies of 19.44,
77.76 or 155.52 MHz
• Internal FIFO to decouple transmit clocks
• Various diagnostic loopback modes
• Quad configuration, mixed OC-3/OC-12
• Built-In Self Test (BIST) Feature
• Independent power down of unused channels
• Drop-in-replacement for S1213
The S1221 SONET/SDH transceiver is one of the
latest additions to the AMCC product family.
The S1221 device provides fully integrated
serialization/de-serialization capabilities with
four independent transceivers. The device
performs all necessary parallel-to-serial and
serial-to-parallel functions in conformance with
the SONET/SDH transmission standards.
Applications
The S1221 can be used to implement the front
end of SONET/SDH equipment which consists
primarily of the serial transmit interface and the
serial receive interface. The Low Voltage LVDS or
LVPECL interfaces guarantee compliance with
the bit-error rate requirements of the Telcordia
and ITU-T standards.

Clock and Data Recovery are provided for the
standard operating rates of 155.52 Mbps (OC-3)
and 622.08 Mbps (OC-12).
The S1221 can also be provisioned to a mix and
match OC-3 and OC-12 data streams within the
same device.
The S1221 can be configured in MII (Media
Independent Interface) mode (MII Mode) or in a
Non-MII mode.

The sequence of operations is as follows for
each Channel:
The S1221 is divided into four Transceiver
modules with each possessing a clock recovery
unit. Each of the modules can run at OC-3 or
OC-12 data rates, independent of the other
modules.
